PLASTICS TECHNOLOGY UNDER CONTROL

www.sise-plastics.com

SISE has been a pioneer in the development of sequential molding. Beginning with the automotive industry (bumpers, dashboards, ...),

we have now extended our expertise to technical parts and consumer packaging

SISE has a complete product line that can handle between 2 and 20 valve gates, from the compact IS’TIMER and simple IS’BASIC to the evolved IS’TECH

which provides standard mold sensor-driven control.

IS’BASIC

SISE has recently developed and sells a new valve gating system, which is independent of the molding machine process and fulfi lls the needs

generated by the development of the sequential molding market.

Our compact system controls between 2 and 12 valve gates and provides the following features : injection start, injection hold & screw stroke position signals,

multilingual interface, 24-fi le Memory, safety alarm, actual screw position monitoring (optional).

PROGRAMMING : Integrated multilingual user interface (keyboard, LED screen), for the following functions :

4 Programmable valve gate operation4 Load / Save 24 sequence fi les4 Manual Valve Gate operation4 Cycle Time Display

Option : 4 Control of actual screw position (limit switches)

CONTROL : Available versions from 2 to 12 valve gates Controls up to 2 openings & closings per valve gate and per injection cycle Each movement can be individually triggered by one of the following signals:

4 On time as a delay from injection start or hold start.4 Screw position in %, in mm, or in cm3.

ALARMS / SAFETY : Alarm output on dry contact, activated in case of:

4 Hydraulic Pressure Failure (not used if no external power pack)4 Injection Safety : at least one gate must be open on cycle start and during cycle4 Control Card Failure

Alarm input from the press and/or from the hydraulic power pack.

CONNECTIONS : Valve Gate Output Command Harting, 32 pins 10A femal Power 24V=, maximum intensity 1.5A by channel Control by limit switch (option) Harting, 32 pins 10A male Input signals Harting, 16 pins 10A female Alarms Harting, 10 pins 10A female Power supply by connection cable 4,5 m long 240V - 50/60Hz



The IS’TECH works well not only with standard applications requiring a high number of valve gates (up to 20), but also with new developments involving mold sensors. Our system manages automatic mold recognition for fast, seamless mold changes.

Thanks to its safety and programming capabilities, our system is the benchmark solution for many automotive applications.

PROGRAMMING : The user interface (keyboard + function keys + blue LCD screen) is embedded in the system and offers the ability to :

4 Program the opening & closing of valve gates as well as their manual control 4 Load / Save 48 sequence fi les4 Display in real-time of both cycle time and part count4 Multilingual (9 standard languages)

CONTROL : From 4 to 20 valve gates Allows 5 openings & 5 closings per injection cycle and per valve gate. Each movement can be triggered individually by any of the following signals :

4 Injection start signal (1/100 sec. accuracy)4 Injection hold signal (1/100 sec. accuracy)4 Dosing signal4 Screw stroke position (programing in %, mm or cm3)4 Injection pressure (in bars)4 Programming with 6 mold sensors (programming in Bars) - Option

Screw stroke position signals (in mm and cm3), the injection pressure as well as the sensors are calibrated specifi cally for each injection molding machine. Machine’s switchover point with events (pressure sensors in the mold) Automatic mold recognition (up to 128 molds) - Option Connection to bi-material machines (management of both screws) - Option Control by limit switch - Option

ALARMS / SAFETY :4 PDM Page : Process Drifting Monitoring (Quality Management, Reference Cycle Backup) 4 1 NC input for power pack failure (bridged input if no external group is available)4 1 NO input for external failure (from the molding machine for example)

The system also handles the injection safety by making sure that at least one valve gate remains open at the beginning of the cycle and that at least one valve gate remains open during the entire cycle.

CONNECTIONS :4 Manifold Control Harting 32 pins 10A Female4 Mold Recognition Signals Harting 25 pins 10A Female4 Alarms Harting 10 pins 10A Female4 Input Signals Harting 16 pins 10A Female + 5 BNC4 Computer Communication USB4 Computer Power Supply 230V

PC CONNECTION : Connecting to a computer is very simple thanks to the USB terminal and the optional Win’IS TECH software that offers the following:

4 «Offl ine» programming of an injection sequence4 External transfer and fi le backup4 Recorded data processing (pressure curves, screw position, input signals…)
